**9. Conclusion**

The paper presented some experimental results allowed to consider that the waveguide-resonance conception is right. We described the features of the waveguide-resonance mechanism discussed its principle model and fixed the critical parameter being responsible for mechanism change of the radiation flux propagation. References presented allowed to understand some practical application of the phenomenon and its consequences. The paper contains the short description of X-ray device functioned on the basis of mechanism – the planar X-ray waveguide resonator, the discussion of PXWR properties, and the ways of its construction perfection.
